DISPENSING-VALVE.

Specification of Letters Patent. A P t t d Ap 192il Application filedDecember 16, 1919. Serial No. 345,418.

T 0 all whom it may concern:

Be it known that I, CHARLES P. Bossnn'r, a citizen of the United States,and resident of Milwaukee, in the county of Milwaukee and State ofWisconsin, have invented certain new and useful Improvements 1n DlS-pensmg-Valves; and I do hereby declare that the following is a full,clear, and exactdevscription thereof.

operation to eject a certain limited quantity of liquid upon eachactuation of the operating member of the valve, and to prevent leakagethrough the valve after a certai amount of liquid has been discharged.

'Such valves are usually provided with a measuring chamber in which isdisposeda plunger to procure ejection of the limited amount of liquid,the valve member being adapted to operate by reason of the velocity flowof liquid to either close off flow of liquid from the reservoir into thevalve, or from the measuring chamber through the discharge port of thevalve. i

It is a furtherobject of my invention to provide an arrangement whereinthe plunger, upon movement in either direction, imparts an initialmovement to the valve member so as to reduce the liability of stickingof the valve member.

With the above and other objects and advantages in View, which willbeapparent as the description proceeds, my invention resides in thenovel features of construc tion, combination and arrangement ofpartswhich will be hereinafter more particularly described and defined by theappended claims.

In the accompanying drawings: Figure 1 is a longitudinal sectional viewthrough a soap dispensing valve constructed inaccordance with myinvention.

Fig. 5 is a similar view on a plane indicated: by the line 5-5 of Fig.1.

:Fig. 6 is an inner end view of the valve.

Referring now more particularly to'the accompanying drawing, my improvedvalve structure comprises an elongated cylindrical casing 10 divided inits intermediate portion by a relatively wide partition 11 to form ameasuring chamber Aat its outer portion, and a valve chamber 13 at itsinner portion, the partition being providedwith a central aperture topermit communication between the chambers. The outlet port 12 of thevalve extends obliquely through the bottom of the wall'of the maincasing 10 at its intermediate portion and opens at the" inner side ofthe partition 11. pluglS is threaded in the valve chamber end of thecasing and is of longitudinal inlet ports l 't and with a nipple portion15 whereby the valve may be secured to any suitable reservoir orothersource of supply. A stem 16 is slidable axially in the plug 15 and isextended through the chambers of the casing and the partition 11, saidstem being threaded into the inner end of a plunger 17 which-is slidablein the measuring chamber end of the casing.

A spring 18 is coiled on the stem within the measuring chamber A andbears against provided with a plurality the plunger and against thepartition 11,

outward movement ofe the plunger being limited bya head 19 on the innerend of the stem 16, said head being adapted to to close the inletpassages 14 of the plug.

A sleeve 20 is slida bly mounted on the stem 16 within the valvechamberB and isprovided at one end with a radial flange 21 adapted to engageagainst theplug 13 and close the inlet ports 14, said sleeve being alsoprovided with a series of longitudinally extending radial ribs 22 whichproject beyond the other end of. the sleeve and carry a disk 23 adaptedto seat against the adjacent face of the partition 11 and close theoutlet port 12, said disk being provided with a central aperture of suchdiameter as not to interfere with free passage of liquid between thechambers. I V

Entering now into the operation 01" my improved valve structure, it willbe seen that the plunger 17 which constitutes the operating member of myvalve and is therefore provided with a suitable headfZei at its outerend, is normally disposed outwardly and the headed end 19 of the stem 16is urged against the plug 18 to provide a positive closure pre ventingpassage of liquid from the reservoir. The disk 23 is also engagedagainst the partition 11, thus closing the discharge port 12 of thevalve and a certain amount of liquid is contained within the measuringchamber A and the valve chamber B. To actuate the valve, the plunger 17is moved inwardly and in this inward movement of the plunger the valvemember will be carried on the stem 16 thus uncovering the discharge port12 and seating the flange 21 against the plug 13 to close the inletports 14-. The amount of liquid displaced by the plunger 17 in itsinward movement is thus forcibly ejected from the valve, and when suchejection has occurred, the valve member will slide on the stem to closethe discharge port 12 by reason of flow of liquid from the reservoir.This movement is however more thoroughly eilected when the plunger 17 isnormally released after being moved to its inward limit of movement,thus causing the plunger to move outwardly under the action of thespring.

" As the plunger moves outwardly, it will draw a successlve charge ofliquid into the measuring chamber, the flow of fluid in either directionthrough the valve chamber serving to move the valve to its selectiveclosing position by impinging against the flange and disk portions ofthe valve member.

I have thus'provided an exceedingly simple and efficient dispensingdevice in which, upon movement of the plunger in either direction theflow of liquid to and from the measuring chamber effectively imparts thedesired moving impulse to the valve member which is reciprocably mountedon the stem of the plunger. It is noted that in the normal closingposition of the valve, a double seal is afforded against leakage throughthe valve, by the disk 23 and stem head 19.

lNhile l have shown and described a preferred embodiment of myinvention, it will be appreciated that various changes and modificationsof structure may be employed to meet differing conditions of use andmanufacture without departing in any manner from the spirit of myinvention.

What is claimed is:

1. A valve structure of the class described comprising a storagechamber, a valve cham ber in communication with the storage chamber, avalve member reciprocable in the valve chamber, inlet and outlet portsfor the valve chamber, a plunger having a stem slidable in the measuringchamber, said valve being slidably mounted on said stem and operable bythe flow of liquid upon reciprocation of the plunger to open and closesaid ports successively.

2. A valve structure of the class described comprising a measuringchamber, a valve chamber in communication with the storage chamber, avalve member reciprocable in the valve chamber, inlet and outlet portsfor the valve chamber, a plunger slidable in the measuring chamber, anda stem secured to the plunger and slidably engaged with the valvemember.

3. A valve structure of the class described comprising a measuringchamber, a valve chamber in communication therewith, a plunger slidablein the measuring chamber, a stem extending from the plunger through saidchambers, a valve sleeve slidable on the stem within the valve chamber,inlet and outlet ports for said valve chamber, and portions carried bysaid sleeve for selectively closing said ports,

4;. A valve of the class described comprising a measuring chamber, avalve chamber in communication therewith, inlet and out let ports forthe valve chamber, a plunger slidable in the measuring chamber, meansresiliently urging said plunger outwardly, a stem extending from saidplunger through the chambers, a head on said stem adapted to close theinlet port of the valve chamber in outward position of the plunger, anda valve member movable in the valve chamber to selectively close saidports.

5.

6. A valve of the class described ,comprising an elongated casingprovided with an intermediate partition apertured to affordcommunication between the consequent measuring and valve chambers formedthereby, a closure for the valve chamber end of the casing, a plungerslidable in the measuring chamber end of the casing, inlet and outletports for the valve chamber, a valve member in the valve chamber movableto selectively close said ports, and a stem extending from the plungerand slidably engaged with the valve member.
